Short communicationNon-esterified fatty acids in early luteal bovine oviduct fluid mirror plasma concentrations: An ex vivo approach

We investigated whether and to which extent plasma non-esterified fatty acids (NEFAs) are reflected in oviduct fluid (OF) using an improved ex vivo flushing method. OF and plasma NEFA concentrations were respectively 0.29 ± 0.19 and 0.31 ± 0.14 mmol/L, they didn't differ significantly (P = 0.13) and tended to be positively correlated (Pearson correlation coefficient = 0.56; P = 0.07). Results suggest that OF NEFAs mirror the concentrations seen in plasma of healthy cattle.
